Checking and Replacing Fuses
WARNING
!
ELECTRIC SHOCK HAZARD
•
Ensure that the power source is off before checking or replacing fuses.
•
Disconnect power from the machinery it is connected to before making any wiring
connections. This includes disconnecting power to the machine control and motor.
•
Ensure that all procedures are performed by qualified personnel.
Failure to comply with these instructions could result in death or serious injury.
Any time Shadow loses power or will not allow press operation, first check the fuses that are
located in the control. They are easy to check and replace.
The fuses are common 3AG glass cartridge fuses (
1/4
" dia. x 1
1/4
" length) listed in Appendix
D. The rating,
1/4
amp and 4 amp, is marked next to the fuse on the circuit board. Here is
how to check the fuses inside the control.
1. Turn off power to Shadow.
Never check or change fuses with the power on.
2. Open the hinged cover of the control by loosening the locking screws.
3. Locate the fuses on the circuit board. Refer to the location of components illustration in
Chapter 2. There are 4 fuses - 1 power (at F1), 2 stop (at location F2 and F3), and 1
status (at F4).
4. Remove the plastic cover over the fuse. Look to see if the metallic strip inside any of the
fuses is broken. Test with an ohmmeter if available. Put the ohmmeter leads on each side
of the fuse. No resistance (0 ohms) means the fuse is good.
5. If the fuse has blown, pop it out of the holder by prying it out at the ends. Snap in a new
fuse.
6. Replace all plastic fuse covers.
WARNING
!
ELECTRIC SHOCK HAZARD
Replace plastic fuse covers after checking or replacing fuses. These covers help reduce the
risk of electric shock.
Failure to comply with these instructions could result in death or serious injury.
7. Close the control. Insert and tighten the locking screws.
